Three Dimension Numerical Simulation Analysis Of The Vibration Influence Control To Blasting In Rock

摘要：

With the ANSYS/LS-DYNA program, three-dimensional mathematical model of charging explosion in rock was established with the method of ALE, and the dynamic modulus of elasticity of rock was inversed by the field monitoring vibration velocity of surface. The simulation and prediction were conducted on the vibration velocity of different measuring points with the inversion model, calculation results and measurement results fit fairly well, And validate the rationality of this numerical model with monitoring data. In the end, this inversion model is used to forecast the security amount of explosive. The method can be used as reference for similar blasting engineering in rock.
